Chart 3D Color

[Ricardo]

Hi all,

I am using a RadChart component and, for each data series shown, I have set a different color. When in 2D, the graphic is painted normally, but when it's is changed to 3D, the colors are back to default. For example, in 2D, the first data series has the red color, but in 3D it back to that blue default color. What should be wrong? Any ideas?

Thanks

Hello Ricardo,

Can you give us more details how you style the data series in your application?

Hi,

thanks for reply.

Here is my code. Assume that the variables "colorList" and "legendList" are already set. The function "map" do the mapping for the series and define them according the "typeGraph" variable. In my application, the user may change the appearance of the chart from 2D into 3D and vice versa, and in every change I make a call to this function.

When in 2D, the color are set according to "colorList". In 3D it does not happen, the series are painted with the default colors (but the legends still painted with the colors in "colorList"). I hope to know what is wrong.

Private colorList As List(of Color)

Private legendList As List(of String)

  

Public Sub map(xBinding As string, bindingList As list(of string), typeGraph As ISeriesDefinition)

  

Dim mapCollection As New SeriesMappingCollection()

  

For i As Integer = 0 To bindingList.count - 1

    Dim serie As New SeriesMapping With {.SeriesDefinition = typeGraph}

    serie.legendLabel = legendList(i)

    serie.SeriesDefinition.Appearance.Stroke = New SolidColorBrush(colorList(i))

    serie.SeriesDefinition.Appearance.Fill = New SolidColorBrush(colorList(i))

    serie.itemMappings.add(New ItemMapping(_bindingList(i), DataPointerMember.YValue))

    serie.itemMappings.add(New ItemMapping(_xBinding, DataPointerMember.XValue))

    mapCollection.add(serie)

Next


chart.SeriesMappings = nmapCollection

  

End Sub

May I do another question? In this change of 2D to 3D, how I make the camera extension work?

Thank you for the help.

Hi Ricardo,

The Appearance API only works with 2D series. Setting the Stroke/Fill properties would have no effect on 3D series. As for enabling the camera extension, please, have a look at our Flexible API example, which demonstrates how to add it when switching to 3D series.

Hope this helps.

Hi again!

So, there is not another way to change the color of a 3D graph? One that should work with 2D too?

Thanks you!

Hi Ricardo,

You can change the color of 3D series by creating a custom palette in a similar way as in our demo Custom Palette example. Please, have a look at the attached sample app, which demonstrates how to achieve this.

Hope this helps.
